Hi Guys, So I modified a TOSlink to coaxial digital converter, to fire a cheap 1mw laser diode instead of the electrical signal. Connected that to the Apple TV TOSlink connector, and the laser can be received directly by the TOSlink input (to an amplifier) at the other end. http://www.youtube.com/watch?v=N5mortSDy1E At the other end, my shelf hifi doesn't have any optical input, so I use another type of converter (TOSlink to analogue Left and Right). The laser can also be shot into an optical cable. What's really interesting is that the ATV provides a DRM free digital audio output. I'm interested in pulling the ancillary information such as track info from the Cirrus decoder chip... this is a bit of a stop on the way Cheers, Art.
